please read safety instructions.
They are
for your protection and should always be
followed to reduce the risk of personal
injury or damage to the tool.
• Always wear proper eye and face protection.
Wear safety glasses or face shields whenever you operate a Foredom or any power
tool to prevent serious eye or face injuries.
• Secure the work piece or item that you are
working on
in a vise or other work holding
device. Holding it with your hand can result
in serious hand injury.
• Always use a proper dust collection system or
wear a respirator
to prevent
the inhalation of
dust particles, polishing compounds, or
other debris into the lungs.
• Do not wear loose fitting clothing or jewelry.
Loose clothing or jewelr
y can become
entangled in the rotating accessory. Do not
wear items such as neckties, necklaces, or
bracelets when operating power tools. Be
tie back or secure long hair.

When properly
Always
find out the
heavy canvas or leather apron. It will protect
you from dust, debris and chips as well as
help prevent injury if the handpiece slips off
the workpiece. It will also help prevent loose
clothing from getting caught in a rotating
cutter, bur or other accessory.
• Never use or continue to use any
accessory which appears to be damaged,
loose, vibrating, or out of balance.
Inspect
each accessory for cracks or flaws before
using it. Avoid knots, imperfections in the
wood or metal objects like nails, which
could damage or catch the accessory.
• Always insert the shank or arbor of an
accessory or mandrel into the collet or
chuck of the handpiece as far as possible in
order to provide proper support and tighten
the collet or chuck securely.
• Never use excessive side pressure which
may bend or break the shank or arbor of an
accessory. Let the speed of the accessory
do the work.
• Do not stall the motor by jamming or using
excessive pressure on the accessory. This
can result in damage to the motor or
flexible shaft.
• Never operate the motor with the outer
sheath removed from the flexible shaft.
• Always disconnect the power cord before
servicing the motor or removing the flexible
shaft or sheath.
• Never operate your power tool during a
perceptible power decrease. Turn power tool
off and do not use until power is
fully restored.
• Use proper grounding procedures. This tool
should be grounded while in use to protect the
operator from electric shock. The tool is
equipped with an approved 3-conductor cord
and a 3-prong grounding type plug to fit the
proper grounding receptacle. The green (or
green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or
green and yellow) wire to a live terminal. If
your unit is for use on less than 150 volts, it
has a plug that looks like sketch A below.
An adapter (sketches B and C) can be used for
connecting plugs as shown in sketch A to
2-prong receptacles. The green colored rigid
ear, lug, etc., extending from the adapter must
be connected to a permanent ground such as
a properly grounded outlet box.
Some jurisdictions, including Canada, prohibit the use
of 3 to 2 prong adapters. Where prohibited,
they should not be used.
Use only 3-wire
extension cords that have 3-prong grounding
type plugs and 3-pole type plugs and 3-pole
receptacles that accept the tool’s plug. Always
disconnect the power cord before servicing
the tool. Never use in an area where
flammable vapors are present.

ever change motor direction while the motor is running.
Changing direction while motor is running can damage the motor or
flexible shaft or lead to premature wear. To turn motor off, remove foot
from foot pedal speed control, or turn dial speed control to
“off”
position, and set rocker switch to “off” (center) position on motor.
